15-Minute Seared Spice-Crusted Mahi-Mahi with Sizzled Corn & Charred Jalapeño Relish
Listen, we are not suffering for dinner tonight. This 15-minute seared mahi-mahi is my ultimate weekday power move when I need something that feels fancy but came together during naptime. The inspiration comes straight from my Brooklyn galley kitchen, where high heat and fast moves are a survival skill. I wanted that Oaxacan depth—hello, toasted ancho and cumin—without spending three hours at the stove. You just rub the fish, slap it in a smoking-hot skillet, and let it do its thing. While the fish rests (crucial step, do not skip unless you want sad, soggy fillets), you throw sweet corn and sliced jalapeño right into those glorious pan juices. Boom. Instant relish. This is a Tuesday dinner, not a wedding banquet. If you can't find mahi-mahi, grab any thick white fish you like—cod or halibut play nice here too. Taste it, add a squeeze of lime, and remember: we eat well around here without losing our minds. Ándale, let's cook.

Timeline
Ingredients
- 1 lb Mahi-mahi fillets(cut into 2 thick portion-sized pieces, patted bone-dry)
- 1 tsp Ancho chile powder(or standard chili powder if in Bodega Mode)
- 0.5 tsp Ground cumin
- 0.5 tsp Garlic powder
- 0.75 tsp Kosher salt(split between fish and relish)
- 2 tbsp Avocado oil(divided; high heat is key here)
- 1.5 cups Sweet corn kernels(fresh stripped off the cob or thawed frozen corn)
- 1 Jalapeño(thinly sliced into rounds (seeded if you want milder heat))
- 3 Scallions(thinly sliced, white and green parts separated)
- 1 Lime(juiced (about 2 tbsp))
- 0.25 cup Fresh cilantro(roughly chopped)
- 1 Ripe avocado(diced)
- 2 tbsp Queso fresco(crumbled (optional finish, or substitute cotija))
Instructions
- 1
Pat 1 lb mahi-mahi fillets completely dry with paper towels (moisture is the enemy of a golden crust!). Mix 1 tsp ancho chile powder, 0.5 tsp ground cumin, 0.5 tsp garlic powder, and 0.5 tsp kosher salt in a small dish, then rub it all over both sides of the fish.
3 min
Tip: Getting the fish dry before spice-rubbing ensures it sears instead of steams.
- 2
Slice 1 fresh jalapeño and the whites/greens of 3 scallions. Have your 1.5 cups sweet corn kernels ready by the stove.
2 min
Tip: Keep greens and whites of scallions together here for a quick pan toss.
- 3
Heat 1 tbsp avocado oil in a heavy skillet (cast iron is best) over medium-high heat until shimmer-hot. Lay down the spiced 1 lb mahi-mahi fillets and sear undisturbed for 3 to 4 minutes until a dark, flavorful crust forms. Flip and cook 2 to 3 minutes more until just cooked through. Transfer fish to a plate to rest.
6 min
Tip: Don't poke or move the fish while it sears! Let the heat do its job.
- 4
In the same hot skillet (don't wipe it out—that spiced browned oil is flavor gold!), add remaining 1 tbsp avocado oil, 1.5 cups sweet corn kernels, sliced 1 fresh jalapeño, sliced 3 scallions, and remaining 0.25 tsp kosher salt. Cook without stirring for 2 minutes to get charred spots, then toss for another 1 minute.
3 min
Tip: Let the corn sit flat for 2 minutes so it gets blistered and sweet.
- 5
Kill the heat under the skillet. Stir in squeeze of 1 juicy lime juice and 0.25 cup chopped fresh cilantro. Spoon the hot sizzled corn relish over and around the resting fish fillets. Top with diced 1 ripe avocado and 2 tbsp crumbled queso fresco. Ándale, lunch is served!
2 min
Tip: Taste it—then decide if you need one more tiny squeeze of lime or salt.
Chef's Notes
We’re not suffering for lunch on a busy workday! Mahi-mahi is sturdy, lean, and cooks in literally six minutes. The trick here is using the leftover skillet drippings from the spice-rubbed fish to char your sweet corn and jalapeños in under three minutes flat. Bodega Mode: frozen corn thawed under warm tap water works every bit as well as fresh cobs. If you want a little extra creaminess, swirl a dollop of Mexican crema or sour cream right on top.
María “Mari” Santiago
Oaxacan comfort, Brooklyn shortcuts, weeknight bright.
María “Mari” Santiago was born in Oaxaca, where her earliest kitchen memories are measured in scent: chiles toasting on a comal, cinnamon and chocolate blooming in mole, and the warm, nutty snap of a tlayuda folded in half for the walk home. She learned by watching—first her tías, then her abuela—picking up the small, practical rules that never made it into written recipes: how to tell when the garlic is *just* right, how to rescue a too-spicy salsa, and why you always taste the broth before you add the salt. Now in Brooklyn, Mari cooks the food she grew up on while raising two little kids and juggling real-life time limits. Her style is “real flavor, real life”: traditional Oaxacan and everyday Mexican dishes—moles, caldos, frijoles, enfrijoladas, salsas, and crispy tlayudas—made weeknight-friendly with smart shortcuts, brighter salsas, and more vegetables without losing the soul of the dish. She’s not precious about rules, she’s big on swaps, and she’s on a mission to prove that you can cook deeply flavorful Mexican food with what you can actually find at a normal grocery store (and still get dinner on the table before a meltdown). Mari’s recipes read like a friend texting you from the produce aisle: clear, funny, and unpretentious, with a side of abuela wisdom. If there’s a hard-to-find ingredient, she gives you a realistic alternative, tells you what will change (and what won’t), and keeps the focus where it belongs—on food that tastes like home, even when home is a small Brooklyn kitchen.
